Abstract

Abstract : The synthesis of new chiral and functionalized vinyl halides from protected L-serinal is described. ... Vinyl halides and terminal alkynes are interesting intermediates in the synthesis of ... We described recently the first synthesis of optically active ethynylglycine ... In that respect, we wish to report our results on the synthesis of new highly ... L-serinal 1.* When dibromovinyl derivative 3 is treated with 1 eq. nBuLi, major ... Exclusive formation of (E) isomer has ...
